이상에서 설명한 바와 같은 본 발명의 드럼세탁기에 따르면, 다음과 같은 효과가 있다.According to the drum washing machine of the present invention as described above, there are the following effects.

청구항 1에 따라서, 작동되는 모터의 종류에 관계없이 드럼의 회전수를 측정할 수 있다.According to claim 1, the rotation speed of the drum can be measured regardless of the type of motor operated.

청구항 2에 따라서, 드럼의 회전을 정확하게 감지할 수 있다.According to claim 2, it is possible to accurately detect the rotation of the drum.

청구항 3에 따라서, 설치가 용이하며, 정확하게 감지할 수 있다.According to claim 3, the installation is easy and can be detected accurately.

도 1은 본 발명의 바람직한 실시예에 다른 드럼세탁기의 사시도.
도 2는 도 1의 센서가 설치된 부분단면도.
도 3은 도 2의 센서의 위치를 변경한 부분단면도.1 is a perspective view of a drum washing machine according to a preferred embodiment of the present invention.
2 is a partial sectional view in which the sensor of FIG. 1 is installed;
3 is a partial cross-sectional view of changing the position of the sensor of FIG.

이하, 본 발명의 바람직한 일실시예를 첨부도면을 참조하여 상세히 설명하면 다음과 같다.Hereinafter, a preferred embodiment of the present invention will be described in detail with reference to the accompanying drawings.

참고로, 이하에서 설명될 본 발명의 구성들 중 종래기술과 동일한 구성에 대해서는 전술한 종래기술을 참조하기로 하고 별도의 상세한 설명은 생략한다.
For reference, the same components as those of the prior art of the present invention will be described with reference to the above-mentioned prior arts, and a detailed description thereof will be omitted.

도 1은 본 발명의 바람직한 실시예에 다른 드럼세탁기의 사시도이고, 도 2는 도 1의 센서가 설치된 부분단면도이고, 도 3은 도 2의 센서의 위치를 변경한 부분단면도이다.
1 is a perspective view of a drum washing machine according to a preferred embodiment of the present invention, FIG. 2 is a partial sectional view in which the sensor of FIG. 1 is installed, and FIG. 3 is a partial sectional view in which the position of the sensor of FIG. 2 is changed.

도 2에 도시된 바와 같이, 본 발명의 드럼세탁기(1)는, 본체(5)와, 상기 본체(5)에 설치되는 드럼(4)과, 상기 드럼(4)의 회전수를 측정하는 센서(2,3)를 포함한다.As shown in FIG. 2, the drum washing machine 1 according to the present invention includes a main body 5, a drum 4 installed in the main body 5, and a sensor for measuring rotation speed of the drum 4. (2,3).

상기 센서(2,3)는 수광부(2) 및 발광부(3)로 이루어진 적외선 센서이다.The sensors 2 and 3 are infrared sensors composed of the light receiving part 2 and the light emitting part 3.

상기 드럼(4)의 외측에는 발광부(3)가 설치된다.The light emitting part 3 is provided outside the drum 4.
